Dear MilesHartog,
I have tried to save a simple mesh section with similar settings, but the fill saved fine for me. I suspect there might be something special about your project that causes this. Can you send me a PLA version of your project so that I can take a look?
I contacted you in a PM, we can exchange files through there.
